Bitcoin may linger on the fringes of the mainstream, but plenty of companies are casting envious eyes towards the technology that underpins it. Just days after IBM announced a plan to use the blockchain as the basis for its own payments platform, Gyft has said that it's doing the same. The digital gift card company has revealed that it's looking into ways to "tokenize" gift cards and issue them on the blockchain for better theft protection. CEO Vinny Lingham has admitted that the company is a long way away from having a working prototype, but it's clear that Bitcoin isn't going anywhere.

Two things define SXSW: spectacle and smoked meat. GE's managed to meld the two at its BBQ Research Center. Just up the street from the Austin Convention Center, General Electric's research arm set up shop with a 12-foot tall sensor-laden super smoker and a BBQ tasting room called Brain on BBQ. As you might suspect, tasters wear consumer-grade EEG headbands (the Muse variety) to track how their brainwaves change when eating savory smoked meat, tangy coleslaw and sweet banana pudding. GE's going to mine the data from every participant to see if it can glean some useful insight about the nuances of flavors, but really it's just a way for folks to see what's going on inside their noggin whilst chowing down. The whole setup is meant to draw attention to the company's R&D efforts in food and neuroscience, and show that GE's technology can be leveraged to improve most any industry.

If you're guaranteed one thing at SXSW, it's that a marketing stunt will play tricks with your stupid human heart. This year, singletons looking for love on Tinder encountered Ava, a 25-year-old New Yorker with a startling resemblance to actress Alicia Vikander. Unfortunately, it's only after you've engaged in a lengthy back and forth that you'll be told that she's not interested in a temporary tumble in Texas. Instead, the whole thing is just a cruel ruse to promote Alex Garland's new film, Ex Machina.

"Asteroid hunters." It sounds like some Hollywood blockbuster / straight-to-DVD "classic" that already exists, but now you, yes you, can be one... from your PC. NASA has launched a desktop app that recruits civilians to help identify asteroids from telescope photography, helped by a special asteroid algorithm. Scientists announced the desktop app at SXSW during in a panel discussion where they elaborated on how muggles citizen scientists were helping their efforts to identify and tag asteroids. The app is another collaboration between NASA and Planetary Resources. (It's apparently all under a Space Act agreement, which is the coolest act we've heard of in a while.)

Google Now only displays useful tidbits of knowledge from a handful of your apps right now, but the flood gates are about to fling wide open. Project director Aparna Chennapragada has revealed that Google plans to release a developer kit that lets any of your apps put their data into Now, not just those with special access. It's not clear exactly when this will turn up, but Chennapragada suggests that there shouldn't be collisions between competing software -- your app usage habits will determine which cards appear. While that may be a tad optimistic (it's easy to see two social networks vying for your attention), there's a good chance that Google Now will become a one-stop shop for things you need to know.

AeroMobil has been around for five years, pursuing the dream of building a functional and (somewhat) practical flying car. Its third-gen prototype was revealed last October, and today at SXSW, AeroMobil CEO Juraj Vaculik revealed a bit more about the company's past and future and the challenges that remain to go from prototypes to fully fledged consumer vehicles - which the company plans to accomplish in 2017.

Twitter isn't the only internet giant that wants to spare you from remembering passwords. Yahoo has just trotted out an optional login process that sends passwords on demand. Sign up and Yahoo will deliver a single-use password to your phone whenever you need to log in -- you can prevent someone from easily hijacking your account no matter what device you're on as long as your handset is nearby. This extra-secure option is only available in the US right now, but there's a good possibility that you'll see it in other countries before long.

Cynthia Breazeal has a pretty impressive resume. She's the director of the personal robotics group at the MIT Media Lab, creator of the landmark Kismet robot and now she's the founder, CEO and chief scientist at Jibo. If you're not familiar with Jibo, take a moment to go check out its incredibly successful Indiegogo page. The goal is to create the world's first "family robot." It's cute, friendly and smart. Or at least, it will be when it's delivered to customers. Breazeal acknowledges that other robots and artificial intelligences have made their impact felt in the home, but they've hardly become ubiquitous. For her the key isn't about building a robot that performs some specific function, but about building a relationship with the family, which is the core of any household.

Austin, we love you. We mutually understand that things should be kept weird (otherwise, life would be boring). With that in mind, we're kicking off the Engadget Live series in the live music capital of the world: 7PM on June 20th at the Austin Music Hall!

Austin's Chaotic Moon, the people behind this damn electricity-shooting helicopter will stun you with another incredible creation. Perhaps you want a life-sized replica of Oprah printed?Re3D's got you covered with the world's largest 3D printer. Building a robot? Charmed Labs' Pixy is a sensor that can teach it to find things and you'll get to check it out. Techjango, which brought us the Darkmatter Xbox laptop, will show off even more gadgets for makers. If that wasn't enough, AF1 Racing will bring its totally electric (and fast!) Zero Motorcycle so you can experience it yourself.

SXSW Interactive can hardly match the significance of CES, MWC or IFA when it comes to consumer electronics launches, but there's always a ton of awesome gear to see. This year, Chaotic Moon's "CUPID" stun copter was perhaps the most shocking innovation, but IBM's Watson-powered food truck, a Leap Motion-equipped Oculus Rift and Neil Young's PonoMusic player also dominated on the gear front. In between hands-on demos, we caught up with Aereo, BlackBerry, Shaquille O'Neal and even Snoop Dogg, while also sitting in on SXSW sessions featuring the likes of Edward Snowden and 23andMe's Anne Wojcicki. We say farewell today, but South-by 2014 will live on for a few days to come, with hundreds of concerts and other events dominating the seemingly countless performance venues in Austin, Texas.Slideshow-184118

With different requirements and countless other incompatibilities, building applications for multiple platforms can be a tremendous chore. Embarcadero Technologies is setting out to simplify that process a bit with Appmethod, a multi-device development platform that lets you create apps for Android, iOS, Mac and Windows simultaneously. The WYSIWYG tool lets you drag and drop buttons, connectors, databases and other design elements into one emulated platform, then easily duplicate the app onto another.

What better way to wrap up SXSW 2014 than with a picnic with Snoop Dogg? We stepped inside Snoop's own mini-apartment, which he designed in partnership with Airbnb, to talk about his favorite gadgets. He's apparently a huge fan of the Avegant Glyph virtual-reality headset, though his temporary pad also includes essentials like a Samsung flat-screen and an Xbox One. One other must-have, which you won't see in our video tour: Snoop's special breakfast sandwich, with Texas toast, eggs, bacon, sausage, cheese and grape jelly. (It's surprisingly good!)Slideshow-184008

To say that BlackBerry's had it tough these past few years would be putting it mildly, if not too delicately for a company emerging from a period of willful ignorance. The Waterloo-based outfit, formerly known as Research in Motion, played an embarrassing game of catch-up in the mobile space it once dominated. An uphill rehabilitation that saw it acquire QNX to build a new operating system, release a half-baked tablet, rebrand as BlackBerry in search of a new identity and, tellingly, hire Alicia Keys as a creative figurehead.

And none of it mattered -- not even the forced infusion of Ms. Keys' questionable zeitgeist-y influence. The BlackBerry of today has so far failed to resurrect sufficient interest in its fledgling mobile platform and devices, leading to the ouster of former CEO Thorsten Heins, the very recent installation of John Chen and a redoubled focus on the enterprise set that once was core to the company's business. So why does the company still seem to be engaged in an internal tug-of-war over its identity? I had a chance to speak with Gary Klassen, longtime BlackBerry employee and principal architect, here at SXSW in the hopes he could shed some light on what the Blackberry of today stands for and where it's going.

We saw Epson's Moverio BT-200 glasses back at CES, and while not much has changed on the hardware front since then, the company dropped by SXSW to demo a few new games. There's also a new homemade camera rig, so it's now possible to share the excitement here. Moverio supports the full version of Android 4.0, but unlike smartphones and tablets running the same OS, these glasses include a pair of embedded transparent displays, which provide a surprisingly usable view, while also preserving some of your field of vision -- we absolutely would not recommend walking, driving or interacting with humans while wearing them, though.

At SXSW today, NSA whistleblower Edward Snowden will make his "first appearance front of a live audience" since he unveiled the under belly of the government surveillance program. Snowden will speak with the ACLU's Ben Wizner and Christopher Soghoian, but as the name suggests, this is a virtual conversation and he will not be appearing in person for the festivities in Austin. The ACLU is liveblogging the entire affair here at 12PM ET and a livestream will be posted over at The Texas Tribune. If you miss out on the live coverage, the ACLU will post a video of the interview afterwords.

Update: We've embedded the livestream after the break.

Update 2: Well, things have wrapped up, but you can relive the conversation after the break.

This is Shaquille O'Neal's second SXSW, and this year he stopped by Austin to talk about wearables. In a panel with Rick Valencia of Qualcomm yesterday, Shaq touched on the importance of activity trackers in keeping us fit. He's personally a fan of Fitbit, which he uses to help meet the goal of 10,000 steps per day, though he told us he's all for any device that keeps users active and motivated. We had a chance to pick his brain about wearable tech in general -- he's all for Google Glass -- and asked him about the other gadgets he relies on when he's on the road. (Spoiler: he carries both an Android handset and an iPhone.) See what else caught his eye at SXSW 2014 in our video interview.

We now know how Neil Young plans to make his dreams of high-quality digital music come true: crowdfunding. The artist's company PonoMusic is launching a Kickstarter campaign on March 15th that will let you reserve the PonoPlayer, Young's long-teased, audiophile-grade portable jukebox. The 128GB device will set you back a whopping $399 when it goes on sale (less with the Kickstarter discount), but its creators are promising audio fidelity worthy of the price tag. The hardware will offer natural-sounding digital filtering from Ayre Acoustics, ESS' most advanced digital-to-analog converter and "perfectly flat" frequency response with most any set of headphones. As you might expect, there will be a matching online store that delivers high-resolution tunes. The PonoMusic team hasn't said just when its media player will reach your pocket, but it shouldn't be too long before you're listening to a pristine version of Harvest while on the move.

It's a bittersweet day in Austin, Texas, for Aereo. The company's remote DVR service, which allows users to stream or record over-the-air broadcasts, just launched in the city this week against the backdrop of SXSW, making it Aereo's fourth market in the state. But there's a storm cloud hanging over this celebration; a recent legal hiccup with the state of Utah that saw it shut down service in Denver, Colo., and Salt Lake City, Utah. Aereo, however, is no stranger to this courtroom drama. The company's been engaged in a copyright battle with broadcasters that'll either cement it as a content licensee (along the lines of a Netflix), and potentially cripple its business growth, or as a provider of cloud DVR storage. It's a fight Aereo's waging all the way to the Supreme Court and has so far been winning, except for today.

SXSW is a veritable playground for journalists, with panels catering to media professionals and -- most importantly -- no shortage of free food. We're not surprised, then, that The New York Times chose Austin as the venue for an announcement this week. Perhaps "tease" is more apt than announcement, though, since we aren't allowed to capture any pictures of the upcoming NYT Now app at this time (the bar menu above was the only documentation we're permitted to publish).

We know Watson has some Jeopardy skills, but putting IBM's supercomputer in the kitchen? That's a little different. Here at SXSW, the company's set up a "Cognitive Cooking" food truck in partnership with the Institute for Culinary Education (ICE). Using Watson's recipe system, which combines three elements (ingredient, cuisine and type of dish) to create unconventional new fare, chefs here in Austin are churning out delicacies such as ceviche fish and chips and Vietnamese apple kebabs.Slideshow-183676

The first few days of SXSW have brought quite a bit of excitement for our team on the ground. After starting the show with a stun-copter demo, we stopped by the Palmer Events Center to play a little a live-action Mario Kart. Pennzoil has set up a go-kart track here in Austin to promote its new Platinum line of natural gas-based motor oils, though -- let's face it -- we were really only here to be Mario (and Luigi, Bowser and Princess Peach) for a day.
